I have seven (7) iPads for sale, all are 16 GB, WiFi only, black, with Retina display (4th gen, current model as of 09/14/2013). I'm selling them on behalf of a small company I work for. We use them to conduct scientific studies for biomedical research. These particular iPads were used at a special-needs school earlier this year.

No scratches on any of the displays that I can see. All of the iPads have some moderate scuffing on the back (in the aluminum), with a few larger scuffs/scratches on a few of them. No dents or deformities on the corners. The wear looks as you'd expect after a few months of moderate use at a grade school without a case. I've included a few pics (below) of a typical back, and close-ups of the worst scuffs/scratches.

Additionally, the boxes have permanent marker ink on the front, where the school teachers marked a letter (e.g., "B") on the box to identify which students were to use it. As such, I've conservatively marked the iPads as "8 - well used" although a few of them are closer to an 8+/9.

All 7 iPads include the original box; 5 of them have the AC adapter and USB-lightning cable, 1 of them is missing the AC adapter, but includes the USB-lightning cable, and the last 1 is missing both the AC adapter and the USB-lightning cable.

Each iPad also includes an Apple Smart Cover, light gray, with no packaging. The covers are in 8+ condition.

Everything is 100% functional, and the cosmetic damage should be entirely hidden if you use a back cover/case. Still covered under original 1-year warranty until late May 2014.

A refurbished iPad 4 with these same specs are going for $419 from Apple. I'd like to sell these for the following:
